Description: Almost all of the Charles E. Fiero Papers reflect varieties of Ojibwe/Anishinaabemowin. Fiero, a missionary linguist, is best known within the field for creating the double-vowel orthography. Series I (the bulk) contains manuscripts, while Series II contains a small volume of digital media that has yet to be transferred. The collection represents fieldwork originally done between 1957 and 1993 (bulk 1957-1970s), chronologically arranged by date of first fieldwork, and contains many retranscriptions and reanalyses by Fiero from subsequent decades, illustrating his understanding of the material. The fieldnotes mostly comprise lexica and texts, and individual folders typically contain detailed background information. Fieldwork was mostly conducted in Ontario. Place names include: Berens River, Deer Lake, Pauingassi, Pikangikum, Poplar Hill, Red Lake, White Earth, Cat Lake, Doghole Bar, Fort Hope, Grassy Narrows, McDowell Lake, North Spirit Lake, and Pickle Lake.
